The Kotlin CLI app to solve quadratic equations

View the code here.

This application is designed to solve quadratic equations of the form $ax^2+bx+c=0$, where $a \neq 0$. It calculates the roots of the equation and displays them. There are two different modes available to use the application:

1. Interactive mode - the application asks the user to enter the coefficients of the equation and prints the roots.

2. Non-interactive mode - the application takes the coefficients from input TXT-file argument and prints the roots.

• Download Kotlin compiler here

• Extract the archive on your computer

• Add the Kotlin bin folder to your system's PATH environment variable. Open the command prompt (CMD) and run the following command:

setx /M PATH "%PATH%;C:\path\to\kotlin\bin"

• Replace "C:\path\to\kotlin" with the path to the folder where you extracted the Kotlin compiler.

NOTE: You can add Kotlin bin folder to your system's PATH environment variable using Windows UI tools. Click here to see the instructions.

• Verify that the Kotlin compiler is installed correctly by running the following command in the command prompt:

kotlinc -version

• Verify that you have Java Runtime Environment(JRE) on your computer

• Clone the project on your computer.

git clone https://github.com/AKushch1337/SDMaT-lab1

• Move into the folder where you cloned the project

• Open the command prompt (CMD) and run the following command:

kotlinc *.kt -include-runtime -d quadratic-equation-solver-cli.jar

NOTE: You can replace quadratic-equation-solver-cli with whatever name you want

• This will generate .jar file which you can run using Java Runtime Environment(JRE)

NOTE: You can skip the "Build the project" part and just download the .jar file =)

• Download here.

java -jar \path\to\runtime\file\quadratic-equation-solver-cli.jar

java -jar \path\to\runtime\file\quadratic-equation-solver-cli.jar \path\to\file\with\inputs

When the application is in non-interactive mode it expects a single argument that specifies the path to the file containing the coefficients of the equation. The file should have three numbers separated by a single space, representing the coefficients a, b, and c of the equation. Here's an example of how the numbers should be formatted in the file.
